An electrical connector is provided, capable of exerting a sufficient clamping force on a flat cable to reliably provide electrical conductivity while the connector is low-profile. The connector includes a contact having a base, a contact beam, and a pressing arm. The pressing force of a cam of an actuator is transmitted to a base through the pressing arm. Thereby, lift of the base is restrained, and a flat cable is reliably clamped, thereby providing electrical conductivity. Also, elastic deformation of the pressing arm reduces the range of variations in the contact pressure of a contact arm of the contact beam caused by the variations in thickness, gap, dimension, and the like.
